9.3 Cell Cycle Regulation
Objectives:• 5(A) describe the stages of the cell cycle, including
deoxyribonucleic acid (DNA) replication and mitosis, and the importance of the cell cycle to the growth of organisms
• 5(D) recognize that disruptions of the cell cycle lead to diseases such as cancer.
The normal cell cycle is regulated by cyclin proteins.
Section 3: Cell Cycle Regulation
Essential Questions• What is the role of cyclin proteins in controlling the cell cycle?• How does cancer relate to the cell cycle?• What is the role of apoptosis?• What are the two types of stem cells and what are their potential
Abnormal Cell Cycle: Cancer• Cancer is the uncontrolled growth and division of cells.• Cancer results when cells stop responding to the controls of the cell
cycle.• Cancer cells can kill an organism by crowding out normal cells,
Apoptosis• Apoptosis is the process of programmed cell death.• Cells going through apoptosis shrink and shrivel.• Apoptosis occurs during development, in cells that are damaged,
Adult stem cells• Found in various tissues in the body • Might be used to maintain and repair tissue.• More developed/specialized than embryonic stem cells, but might
be able to differentiate into different kinds of cells.
